Exposure of a certain fruit fly population to an insecticide has produced 2 kinds of mutations. 20% have wing mutation, 15% have an eye mutation and 5% have both. A fly is selected at random. a) If it has the wing mutation, what is the probability that it also has the eye mutation? b) If it has the eye mutation, what is the probability that it also has the wing mutation? c) What is the probability that it has at least one of the mutations?
